SimplePicker widget is not rendering the Nested List of JSON array.

[satheeshkumar]

Hi All,

I have a SimplePicker widget, the sample code is shown below,

var imageLibraryPicker = {   name : "alfresco/forms/controls/SimplePicker",   config : {      label : "Pick Image Libraries",      description : "This is a simple picker publishes a request to get data to display",      visibilityConfig : {         initialValue : false,         rules : [ {            targetId : "SHOW_OTHER_FIELDS",            is : [ true ]         } ]      },      name : "imageLibraries",      noItemsMessage: "No Libraries Available!",      loadDataPublishTopic : "ALF_CRUD_GET_ALL",      loadDataPublishPayload : {         url : "retrieve-library-list?retrieve=Image%20Library"      },      itemsProperty : "imageLibrariesList.image",      itemKey : "prop_cm_name",      propertyToRender : "prop_cm_name",      availableItemsLabel : "Available",      pickedItemsLabel : "Currently Selected"   }};‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

My Sample JSON Nested Array response rendered by my webscript URL

http://localhost:8080/alfresco/service/retrieve-library-list?retrieve=Image%20Library‍

is,

{  "imageLibrariesList": [    {      "image": [        {          "prop_cm_name": "Images1"        },        {          "prop_cm_name": "Images2"        }      ]    },    {      "background": [        {          "prop_cm_name": "Background2"        },        {          "prop_cm_name": "Background1"        }      ]    },    {      "stock": [        {          "prop_cm_name": "Stock1"        },        {          "prop_cm_name": "Stock2"        }      ]    },    {      "photo": [        {          "prop_cm_name": "Photo1"        },        {          "prop_cm_name": "Photo2"        }      ]    },    {      "graphics": []    }  ]}‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

I was expecting

Images1‍

and

Images2‍

would be rendering as per the above configuration, but it is not rendering anything and showing

Could not load properties‍

Can someone let me know, is there anything wrong in my JSON response or the way I access

itemsProperty : "imageLibrariesList.image"‍

.

Thanks in Advance,

Here is the Simple JSON Array List(i.e Non Nested compared to my previous post),

{  "stockImagesLibraryList": [    {      "prop_cm_name": "Stock2"    },    {      "prop_cm_name": "Stock1"    }  ],  "backgroundImagesLibraryList": [    {      "prop_cm_name": "Background2"    },    {      "prop_cm_name": "Background1"    }  ],  "photoImagesLibraryList": [    {      "prop_cm_name": "Photo1"    },    {      "prop_cm_name": "Photo2"    }  ],  "imagesLibraryList": [    {      "prop_cm_name": "Images2"    },    {      "prop_cm_name": "Images1"    }  ],  "graphicsImagesLibraryList": []}‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

And I am able to access this properly with the below SimplePicker,

{   name : "alfresco/forms/controls/SimplePicker",   config : {      label : "Pick Image Libraries",      description : "This is a simple picker publishes a request to get data to display",      visibilityConfig : {         initialValue : false,         rules : [ {            targetId : "SHOW_OTHER_FIELDS",            is : [ true ]         } ]      },      name : "imageLibraries",      noItemsMessage: "No Libraries Available!",      loadDataPublishTopic : "ALF_CRUD_GET_ALL",      loadDataPublishPayload : {         url : "retrieve-library-list?retrieve=Image%20Library"      },      itemsProperty : "imagesLibraryList",      itemKey : "prop_cm_name",      propertyToRender : "prop_cm_name",      availableItemsLabel : "Available",      pickedItemsLabel : "Currently Selected"   }};‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

It looks like, I am not able to access the Nested JSON Array in Simple Picker,
Please guide me if I am wrong.

Thanks in Advance,

It should still be possible to access an array element if you are 100% sure that the index will never change, e.g. you could set itemsProperty to be "imageLibrariesList.0.image" (this assumes that the "image" object will always be the first element in the "imageLibrariesList" array). However, a better solution would be to use a custom service (rather than the CrudService) so that you can "normalize" your data into whatever data structure you require.
